    摘要: A heat energy recovery system includes an evaporator, a superheater, an expander, a power recovery device, a condenser, a pump, and a controller. The controller includes: an engine load calculation section; a maximum rotation speed determination section for determining a maximum rotation speed of the pump which is obtained when a pinch temperature reaches a target pinch temperature, based on a relational expression representing a relationship between the engine load and the maximum rotation speed, and an engine load; and a rotation speed regulation section for regulating the rotation speed of the pump in such a way as to allow the degree of superheat of the working medium flowing into the expander to be equal to or greater than a reference value, and to allow the rotation speed to be equal to or less than a maximum rotation speed determined by the maximum rotation speed determination section.

    摘要: Provided is a marine propeller that strikes a favorable balance between suppressing cavitation at a blade tip and avoiding stress concentration in a propeller blade. Two inflection points are provided in a rake distribution of a propeller blade (10) of a marine propeller, where a portion from a blade root section (11) to the first inflection point (12) has a backward rake and a portion from the first inflection point (12) to the second inflection point (13) has a forward rake. The portion from the second inflection point (13) to a blade tip (14) has zero rake so as to be orthogonal to the propeller shaft line A-A. The first inflection point (12) is preferably at a position that is 40 to 60% of the propeller radius, and the second inflection point (13) is preferably at a position that is 80 to 95% of the propeller radius.
